How it works

Tap. Tap. Tap. Done.

PUP isn't a journal app you abandon in week two. Logging takes seven seconds, and the longer you stick with it, the more the patterns surface. He'll cheer you on.

Seven-second logs

Bristol type, duration, toilet, optional GPS — all from one sheet. Works offline; syncs when you're back online.

Patterns over time

A month calendar coloured by Bristol type, deep stats with distribution charts, and a Poop Score that tells you how regular you actually are.

The Bristol scale

Seven shapes. One healthy zone.

The Bristol Stool Scale is the clinical chart used worldwide to classify stool consistency. PUP speaks Bristol so what you log actually means something. Aim for Type 3 or 4 — that's the green zone.

Inside the app

Designed for the three-tap log.

Every screen has one job. The home calendar is glanceable. The add sheet is a single column you can tab through one-handed. The detail view tells you whether today's log is normal — and what to do if it isn't.
